@EnableFeignClients(clients = UserClient.class,defaultConfiguration = DefaultFeignConfiguration.class)//启动类添加注解开启Feign的功能-自动装配功能

//@EnableFeignClients(basePackages = "cn.itcast.feign.clients")指定Feign应该扫描的包：这个是全指定，解决feign找不到的问题
//@EnableFeignClients(clients = {UserClient.class})指定需要加载的Client接口：这个是精准指定用哪个就指定哪个-上面用的就是这个
